MAX30102 Heart Rate Oxygen Pulse Sensor Oximeter Module

Maxim Integrated MAX30102 High-Sensitivity Pulse Oximeter and Heart-Rate Sensor for Wearable Health Monitoring. Measures the SpO2 oxygen saturation in a person's blood useful detecting respiratory illnesses early through wearables and medical monitoring.

Specifications:

• Heart-Rate Monitor and Pulse Oximeter Sensor
• To monitor SpO2 blood oxygen level and heart rate, place a person's fingertip, wrist, earlobe, or other pulse-monitoring location on the sensor

• Operating Voltage: 1.8V to 5.5V (1.8V power supply and a separate 5V power supply for internal LEDs. Onboard voltage regulator takes the power from a single supply on the VIN pin and regulates it so a single source can power both the sensor and the internal LEDs.)
• Pinout:
• VIN: 1.8V to 5.5V
• SCL: I2C Clock Signal
• SDA: I2C Data Signal (bidirectional)
• INT: MAX30102 active-low interrupt open-drain
• IRD: MAX30102 IR LED Cathode and LED Driver connection point
• RD: MAX30102 Power Supply (Anode Connection) for red led
• GND: 0V Ground (connected to IR LED Anode internally)
• Arduino & Raspberry Pi Compatible 
• Digital Output
• Serial Protocol: I2C
• Small Form Factor: 5.6mm x 3.3mm x 1.55mm 14-Pin Optical Module
  
• Integrated protective glass over the sensor for a robust and durable design
  
• Ultra-Low Power Consumption ideal for Mobile Wearable Devices
  
• Programmable Sample Rate and LED Current for Power Savings
  
• Low-Power Heart-Rate Monitor (< 1mW)
  
• Ultra-Low Shutdown Current (0.7uA, typ)
